Q: After Lori dies, Rick goes through a total mental breakdown. What's it like to lose your mind?

A: If they kill my wife, you know what I mean, it's the real deal for me. She deserved everything. I came into the writers' room and said, "What do you think Rick's breaking point is?" And this is what they came up with. I wanted to drop the gun, I wanted to fall, all of these things, and I wanted you to see this man who has led these people and been so strong, fall to the ground broken. I had an acting teacher who always said that even when you're ripping your guts out with emotion, it should be catharsis. Not many people get to do that in their lives full-stop.

Q: In Episode 8, Rick finally gets to see Woodbury. What was your take on the town?

A: I hate Woodbury! I actively feel nauseous when I go there. I hate everybody in it, I just can't stand to look at the place. I love the prison, it's beautiful.
